CASINH(3) Linux Programmer's Manual CASINH(3) NAME
casinh, casinhf, casinhl - complex arc sine hyperbolic SYNOPSIS
#include <complex.h> double complex casinh(double complex z); float complex casinhf(float complex z); long double complex casinhl(long double complex z); Link with -lm. DESCRIPTION
These functions calculate the complex arc hyperbolic sine of z. If y = casinh(z), then z = csinh(y). The imaginary part of y is chosen in the interval [-pi/2,pi/2]. One has: casinh(z) = clog(z + csqrt(z * z + 1)) VERSIONS
These functions first appeared in glibc in version 2.1. ATTRIBUTES
